  摘要：

  摘要α-葡萄糖苷酶抑制剂被广泛应用于糖尿病（DM）的口服治疗，DM是一种以高血糖（高血糖症）和碳水化合物代谢异常为特征的疾病。在这方面，受铜催化的一锅叠氮化/点击组装方法的启发，合成了一系列 1,2,3-三唑-1,3,4-噻二唑杂化物 7a-j。对所有合成的杂交化合物进行了抑制α-葡萄糖苷酶的筛选，结果显示，与 IC50 为 844.81 ± 0.53 μM 的阿卡波糖（参照物）相比，这些杂交化合物的 IC50 值在 63.35 ± 0.72 到 613.57 ± 1.98 μM 之间。在噻二唑分子的苯基环上具有 3-硝基和 4-甲氧基取代基的杂交化合物 7h 和 7e 是该系列中活性最好的杂交化合物，其 IC50 值分别为 63.35 ± 0.72 μM 和 67.61 ± 0.64 μM。对这些化合物的酶动力学分析表明它们具有混合抑制模式。此外，还进行了分子对接研究，以深入了解这些强效化合物及其相应类似物的结构-活性关系。

  A series of 5-substituted-1,3,4-thiadiazole-based fluoroquinolone derivatives were designed as potential antibacterial and anticancer agents using a molecular hybridization approach. The target compounds 16-25 were synthesized by reacting the corresponding $N$-(5-substituted-1,3,4-thiadiazol-2-yl)-2-chloroacetamides with ciprofloxacin or norfloxacin. The purity and identity of the synthesized compounds were determined by the use of chromatographic and spectral techniques (NMR, IR, MS, etc.) besides elemental analysis. Antibacterial, antituberculosis, and anticancer activity of the target compounds were evaluated against selected strains and cancer cell lines. Compound 20 was appreciated as the most active agent representing antibacterial activity against Escherichia coli and Staphylococcus aureus with MIC values of 4 $\mu $g/mL and 2 $\mu $g/mL, respectively. Amongst the synthesized fluoroquinolone derivatives, compounds 19 and 20were found to have modest antitubercular activity with 8 $\mu $g/mL MIC values for each. Most potent derivative, compound 20 was docked against Staphylococcus aureus and Mycobacterium tuberculosis DNA gyrase enzymes to visualize the possible conformation of the compound. Additionally, anticancer activities of target compounds were evaluated on seven different cancer cell lines.

  一系列5-取代-1,3,4-噻二唑基氟喹诺酮衍生物被设计为潜在的抗菌和抗癌药物，采用分子杂交方法。目标化合物16-25是通过将相应的 $N$-（5-取代-1,3,4-噻二唑-2-基）-2-氯乙酰胺与环丙沙星或诺氟沙星反应合成的。合成化合物的纯度和身份通过色谱和光谱技术（NMR、IR、MS等）以及元素分析确定。目标化合物的抗菌、抗结核和抗癌活性针对选定的菌株和癌细胞系进行了评估。化合物20被认为是最活跃的抗菌剂，对大肠杆菌和金黄色葡萄球菌的MIC值分别为4 $\mu $g/mL和2 $\mu $g/mL。在合成的氟喹诺酮衍生物中，化合物19和20被发现具有适度的抗结核活性，每个化合物的MIC值为8 $\mu $g/mL。最强大的衍生物，化合物20与金黄色葡萄球菌和结核分枝杆菌DNA拓扑异构酶酶对接，以可视化化合物的可能构象。此外，目标化合物的抗癌活性在七种不同的癌细胞系上进行了评估。

  A series of thiadiazole derivatives were synthesized with differently substituted benzoic acids which were cyclized to give differently substituted thiazolidin-4-one. Elemental analysis, IR, $^1H$ NMR, $^13}C$ NMR and mass spectral data confirmed the structure of the synthesized compounds. The derivatives of these moieties were evaluated for anticonvulsant activity by MES model and neurotoxicity by rotarod method. The synthesized compounds showed good potential for anticonvulsant activity besides this, the compounds also showed neurotoxic effect. It was observed that compounds with $OCH_3$ at 3, 4 position of phenyl ring [5(a-l)] showed less protection against convulsions as compared to compounds having unsubstituted phenyl ring [4(a-l)].

  一系列噻二唑衍生物通过不同取代的苯甲酸环合得到不同取代的噻唑烷-4-酮。元素分析、红外、$^1H$ NMR、$^13}C$ NMR 和质谱数据证实了合成化合物的结构。这些基团的衍生物通过MES模型评估了它们的抗惊厥活性，并通过旋转棒方法评估了神经毒性。所合成的化合物显示出良好的抗惊厥活性潜力，此外，这些化合物还表现出神经毒性效应。观察发现，相比于具有未取代苯环的化合物[4(a-l)]，在苯环3, 4位带有$OCH_3$的化合物[5(a-l)]对抗惊厥的保护作用较弱。

  A series of thiadiazole derivatives were synthesized with differently substituted benzoic acids which were cyclized to give differently substituted thiazolidin-4-one. Elemental analysis, IR, $^1H$ NMR, $^13}C$ NMR and mass spectral data confirmed the structure of the newly synthesized compounds. The derivatives of these moieties were evaluated for antimicrobial activity. Most of the synthesized compounds showed good antimicrobial activity at 200 and $100\;\mu}g/mL$. Compounds showed most significant antibacterial activity against gram negative test organism Escherichia coli and most significant antifungal activity against test organisms Aspergillus niger and Candida albicans. It was observed that compounds with $OCH_3$ at 3, 4 position of phenyl ring [5(a-l)] were more potent against microbes as compared to compounds having unsubstituted phenyl ring [4(a-l)].
